Facebook has asked agents from the U.S. Drug Enforcement Administration to stop setting up phony accounts using real names.

The social media giant sent a letter to DEA chief Michele Leonhart following a Buzzfeed report revealing that a DEA agent impersonated a woman whose phone was seized during a drug investigation, reported CNN Money.

The U.S. Department of Justice defended Timothy Sinnigen, saying the agent had a right to use photos of the scantily clad woman to set up a Facebook account he used to communicate with other drug suspects.
